VATS Partial Pleurectomy Versus VATS Pleural Abrasion
Introduction: Surgical treatment of primary spontaneous pneumothorax (PSP) usually consists of bullectomy and any form of pleurodesis to reduce risk of disease recurrence. Whether pleurectomy is superior to pleural abrasion is still a matter of debate with recurrence rates especially high when performed with a video-assisted thoracoscopic (VATS) approach.

Talc as an anti-wear functional filler in glass-ionomer cements
To address this issue, we propose the use of a non-toxic solid lubricant, magnesium hydrosilicate (talc), in the form of 5–60 µm lamellar microparticles as a potential anti-wear and anti-cariogenic filler of GICs. In vitro characterization of a GIC modified with 5 wt% of talc demonstrated a 50 % reduction in its tribological wear. The ...
